TIRE-ROLLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 401,? 13, dated April16, 1889.

Application filed September 17, 1888. Serial No. 285,565. (No model.)

To all whom it may concern:

Be it known that I, JAMES MUNTON, a citizen of the United States,residing in Maywood, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Tire-Rolling Machines, of whichthe following is a specification.

My invention relates to improvements in the manufacture of tires fromblooms, as set forth and described in Letters Patent of the UnitedStates, Nos. 363,842 and 363,843, granted to me May 31, 1887, and No.381,505, granted to me April 17,1888. As described in said patents,after the annular bloom is cast, its top portion is sheared or cut oifby revolving rolls having cutter flanges or collars, and then thesheared bloom is edged in, densitied, and rolled to the requireddiameter by a rollingmachine having vertical and horizontal rolls tooperate upon all four faces of the bloom or tire either simultaneouslyor consecutively.

My present invention consists in combining with the shearing or cuttingrolls a stop or device to limit the approach of the cuttingrolls towardeach other, so that the cuttertlanges of the rolls may come suiiicientlyclose together to sever the annulus from the bloom, and at the same timeprevent the cutters from injuring each other by being forced 'togetherso that they strike or touch.

It also consists in combining with the ver tical cutter-rolls a pair ofhorizontal edgingrolls, which may be brought into play the moment theshearing or cutting operation is completed and the severed annulusremoved, so that in this way, without removing the bloom from the millor machine containing the cutter-rolls, the rolling operation anddensification of the bloom may be continued as long as the bloom retainssufficient heat. lVhen the cutting operation is completed,thecutting-flanges of the cutter-rolls span or almost span the horizontalthickness of the bloom, so that no more rolling can then be done by thecutter-rolls without causing the opposing cutter-flanges to meet orstrike against each other; but by combining in the same mill with thevertical cutter-rolls a pair of horizontal edging-rolls the rolling andden sification of the bloom may be indefinitely continued at the sameheat that the cutting is done, as the first effect of the horizontal oredging rolls which bear against the top and bottom faces of the bloom isto diminish the vertical thickness of the bloom and to increase itshorizontal thickness; and as soon as the horizontal thickness has thusbeen increased sufficiently to prevent the opposing flanges of thecut-termolls from meeting the cutter-rolls may be again broughtinto playand operated simultaneously, or, if desired, alternately, with theedging-rolls.

It also consists in combining with the cutter-rolls and edging-rolls twoexterior pressure-rolls, which tend in their operation to density thebloom and roll the bloom backward or to a smaller diameter, or to holdit at a fixed diameter under the action of the edging and cutter rolls.These two exterior pressure-rolls operate in conjunction with theexterior cutter-rolls. By this combination of the edging-rolls and theexterior rolls with'the cutter-rolls the rolling and densification ofthe bloom maybe continued to any desired extent at the same heat withthe cutting operation, and a bloom or tire may thus be produced of muchsuperior density, quality, and texture to the ordinary hammered bloom,as the fraying and injurious eitects of hammering are entirely avoided.

My invention also consists in mounting the inside vertical pressure-rollor its shaft on a separate slide from that which carries either or bothof the edging-rolls, so that the downward or vertical pressure whichoperates the movable edging-roll will not increase the friction of thehorizontal slide which carries the inside vertical pressure or cutterroll in cases where the edging and rolling operations are being carriedon simultaneously.

My invention also consists in mounting the two horizontal edging-rollsand the hydraulic cylinder for operating the movable or pressureedging-roll inthe same horizontally-sliding frame upon which the twoexterior pressure-rolls are carried, so that downward or verticalpressure upon or between the edgingrolls will not increase the frictionof the horizontally-sliding frame when the edging-rolls and the exteriorpressure-rolls are brought to bear simultaneously upon the tire, as issometimes desirable.

My invention also consists in the novel devices and novel combinationsof parts and devices herein shown and described, and more particularlypointed out in the claims.

I11 the accompanying drawings,which form a part of this specification,and in which similar letters of reference indicate like parts, Figure 1is a side elevation of a machine or mill embodying my invention. Fig. 2is a plan view. Fig. 3 is an end view. Fig. 4c is a verticallongitudinal section. Fig. 5 is a cross-section on line 5 5 of Fig. 2.Figs. 6 and 7 are cross-sections on lines 6 (i and 7 7 of Fig. 2. Fig. 8is a detail plan view. Figs. 9 and 10 are cross-sections of the tire,showing its form after the shearing operation is completed and afterbeing operated upon by the edging-rolls, respectively, and illustratingthe action of the edging-rolls to increase the horizontal thickness ofthe tire, so that the flanges of the cutting-rolls will not meet. Fig.11 is a vertical section showing ordinary box-rolls, which may besubstituted for the cutter-rolls when the mill is being used for rollingor finishing tires or rings.

In the drawings, A represents the frame or bed of the machine; B and B,the cutter-rolls; O C, the two exterior pressure-rolls, and D D thehorizontal or edging rolls.

The cutter-rolls B B are preferably both furnished with cutter-flangesor bevel-collars Z) I), the combined width of the flanges b b be ingequal to the horizontal thickness of the bloom when the cuttingoperation is completed. The shaft B of the exterior cutterroll, B, isjournaled in stationary bearings B on the main driving-frame A, and itis driven from the main driving-shaft E through the bevel-gears l and EIts lower end is supported in a vertically and longitudinally adjustablecup-shaped box or hearing, B, the adjustment of which is effected by thewedge B and the screws B and B The shaft B of the movable cutter-roll Bis j ournaled in bearings B B on the horizontal slide or carriage F,which reciprocates on suitable guides, F, on. the main frame of themachine. The slide F is connected by rods or bars F with the piston F ofthe hydraulic cylinder F, by which said slide F is reciprocated to forcethe cutter-roll B against the bloom in opposition to the roll B.

The movement of the movable or pressure roll B is limited by anadjustable stop, f, so that the cutter-flanges b b of the rolls B B mayapproach sufficiently near to sever the top portion or annulus of thebloom and still not quite meet and thus injure each other. This stop fpreferably consists of a screw threaded in the barf which is secured tothe frame A by the rods f f' The screw is furnished with a hand-wheel, ffor turning it, and with a jam-nut, f

The rolls 0 C and the edging-rolls D D are preferably all carried by ormounted upon the same slide or carriage, G. The slide G is reciprocatedin suitable guides, G, on the main frame of the machine by a hydrauliccylinder, G the piston G of which is connected to said slide. Thevertical rolls 0 C and the horizontal roll D are all three journaleddirectly on the slide G; but the vertically-movable horizontal roll D isjournaled in suit able bearings, D on a vertically-reciprocatingsupplemental slide, H, carried on the slide G.

The supplemental slide H is reciprocated (see Figs. at and 6) in itsguides H on the sliding frame G by a hydraulic cylinder, H and piston Hthe stem H of the piston being connected to the slide H. An adjustablestop, h, limits the vertical movement of the edging-roll D, so that thetire or bloom may be edged down to any desired width. This stop 71preferably consists of a handwheel nut on a screw-threaded stein, 7L,secured to the piston H". As the two opposing horizontal or edging rollsD and D and the hydraulic cylinder H for forcing them together, aremounted upon or carried by the same main slide or carriage, G, thepressure of the rolls D and Dwill oppose and neutralize each other andnot be exerted against the guides G of the slide G, nor in any wayincrease the friction or the force required to reciprocate said slide Gon the main frame A.

The vertically non-movable edging-roll D is journaled in bearings D onthe reciprocating slide or carriage G, and it is driven from the maindriving-shaft E through the spurgears E E and shaft E, which shaft isconnected to the shaft D of said roll D by a hollow shaft or sleeve, D,having a spline, (Z, to permit the reciprocating movement of the slide Gand shaft D The bearings C C of the two vertical rolls 0 C are mountedadjustably on the slide G, Figs. 1 and 2, so that they may be'adjustedcloser together or farther apart, as may be required in "rolling tiresof different diameters. This adjustment is preferably effected byfurnishing the slide G with slots 0, in which the bearings or boxes Cfit-,the position of the boxes in the slots being adjusted by a seriesof thin blocks, plates, or wedges, 0, as indicated in Fig. 2.

K K, Fig. 2, are a pair of exterior guiderolls mounted on adjustableslides K K, which reciprocate on transverse guides 011 the main frame A.The positions of the guiderolls are adjusted by screws 7e 75, havingsprocket-wheels k W, chains 76, and sprocket-wheels 70 70 on the shaftis, which is furnished with a hand-wheel, 7t, for turning it.

L L represent the pipes by which the water or fluid under pressure isadmitted to the hydraulic cylinders F G and H from the pumps andaccumulator customarily employed in tire-rolling mills for operating thepressure or movable rolls. Valves L control the admission or escape ofthe fluid-pressure as required.

The cutter-rolls B B are removably secured upon their shafts, so thatthey may be removed and replaced by others when worn or when required inrolling blooms or tires or rings of different sizes and cross-sections.The cutter-rolls B B may also be removed and replaced by ordinary box orother rollssuch, for example, as shown in Fig. 1lwhen it is desired touse the same mill for plain rolling as contradistinguished from cuttingand rolling. 1

The shaft of the movable or pressure roll B and the shaft of the movableor pressure edging-roll D are not driven except by friction with thetire or bloom being rolled. In practice I have also not found itnecessary to drive the vertical rolls 0 C except by friction with thetire.

In operation thebloom the top of which is to be cut off is first placedin the mill and the cutter-roll B forced up against it by thefluidpressure admitted int-o cylinder F As the cutting operationproceeds under the action of the cutter flanges or collars Z) l), therolls B B also roll the bloom, increasing its diame ter and diminishingits horizontal thickness. After the cutting operation is completed theannulus severed from the bloom is removed with a crane, and then theslide G is advanced until the edgingrolls D D are brought astride of thebloom, when the pressure is admitted int-o the hydraulic cylinder H andedging-roll D forced down upon the tire, the pressure being relieved atthis time upon the inside cutter-roll, B. After the edging operation iscontinued for a while the horizontal thickness of the tire will bethereby so increased, as indicated in Figs. 9 and 10, that thecutter-r0ll B may be again brought into play without causing thecutter-flanges to meet and injure each other. At the same time with theedging operation the exterior pressure-rolls, O C, may also be broughtinto play to further densify the metal.

By mounting the hydraulic cylinders F" and G at opposite ends of themachine the slides which carry the various movable or pressure rolls maybe more conveniently operated. The connecting-rods F which connect theslide F with its operating-piston F pass astride of the stationaryexterior roll, B, and its shaft.

hen the mill or machine is being used for plain rolling or finishing thebloom intoa tire, plain rolls being substituted for the cutter-rolls B B011 the shafts B B the stop f is set so as to gage the horizontalthickness of the tire by limiting the movement of the insidepressure-roll toward the exterior stationary roll. This stop f thusserves a very useful and important function, especially,

where the inside pressureroll is operated by a hydraulic cylinder andpiston, as contradis' tinguished from a screw. By means of this stop Iam enabled to prevent any wavy irregularities in the horizontal thickness of the tire, which might otherwise be occasioned by the hydraulic orsomewhat elastic pressure which forces the inside pressure-roll againstthe tire. By means of this stop f, in combination with the stop h, whichlimits the movement of the vertical pressure-roll, the verticalthickness and the longitudinal thickness both of the tire may beaccurately gaged and limited, so that the finished tire may be made veryuniform.
